Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bore maintenance, in particular to an electromagnetic gun bore wiping device. BACKGROUND

[0002] The electromagnetic gun is an advanced kinetic energy weapon made by using electromagnetic launching technology. Unlike traditional cannons that use the pressure of gunpowder gas to act on the projectile, the electromagnetic gun uses the Ampere force generated by the electromagnetic field in the electromagnetic system to accelerate the cannonball to the required kinetic energy for striking the target. Compared with traditional cannons driven by gunpowder, the electromagnetic gun can greatly improve the speed and range of the cannonball. The electromagnetic gun has been widely researched and developed in the military field; the high precision and high speed of this weapon system make it one of the important equipment in future wars.

[0003] After long-term use, the inner wall of the bore of the electromagnetic gun is prone to accumulate dirt and residues, which seriously affects the shooting performance and service life. Therefore, it is particularly important to regularly maintain and clean the bore.

[0004] The traditional method of cleaning the inner wall of the bore of the cannon is usually a manual wiping method. The operator uses a long rod tool with a cloth or other wiping material at the end, and pushes the tool into the bore to wipe it by hand. Some automatic wiping devices in the related art use cylinders or motors as driving members to drive the wiping rod to move back and forth or rotate, and the wiping head can rotate, using the brushes provided on the wiping head to achieve the purpose of cleaning the bore.

[0005] Although the above method can complete the cleaning of the inner wall of the bore to some extent, it still has obvious shortcomings. The manual method is time-consuming and labor-intensive, with low work efficiency; and for the bore of the electromagnetic gun with special internal structure, the automatic wiping device in the related art cannot be used, mainly because some electromagnetic guns have guide rails inside instead of a standard cylindrical shape, forming a flat internal space. The wiping head cannot be matched with it to rotate, and the wiping head also cannot effectively cover all corners, resulting in incomplete cleaning. In addition, the length of the existing wiping rod is limited, and it is also difficult to adapt to longer size electromagnetic gun bores. CONTENT OF THE INVENTION
